Dear libvirt experts，
I have add some patch as follow.this two patch add buffer size to avoid to produce “nl_recv returned with error:No buffer space available” 1. libvirt-nodedev-Increase-the-netlink-socket-buffer-size-to-t.patch 2. libvirt-util-increase-libnl-buffer-size.patch but as I set some configuration in /etc/libvirt/libvitd.conf as follows # Logging level: 4 errors, 3 warnings, 2 information, 1 debug log_level =2 # Multiple outputs can be defined, they just need to be separated by spaces. # e.g. to log all warnings and errors to syslog under the libvirtd ident: log_outputs="2:syslog:libvirtd" when I input “udevadm trigger” command [root@localhost ~]# vi /etc/libvirt/libvirtd.conf [root@localhost ~]# systemctl restart libvirtd [root@localhost ~]# udevadm trigger [root@localhost ~]# udevadm trigger [root@localhost ~]# udevadm trigger [root@localhost ~]# then will produce “nl_recv returned with error:No buffer space available” [root@localhost ~]# tail -f /var/log/messages | grep buffer Sep 2 22:44:00 localhost libvirtd: 4004: error : virNetlinkEventCallback:699 : nl_recv returned with error: No buffer space available Sep 2 23:11:33 localhost libvirtd: 4004: error : virNetlinkEventCallback:699 : nl_recv returned with error: No buffer space available Sep 2 23:11:45 localhost libvirtd: 4004: error : virNetlinkEventCallback:699 : nl_recv returned with error: No buffer space available So my question is: When input “udevadm trigger” in terminal, if setting log_level and log_outputs="2:syslog:libvirtd",how to avoid to produce “error virNetlinkEventCallback:699 : nl_recv returned with error: No buffer space available” log information? I am looking forward to your reply. _____ Best Regards, Jidong Xia China Mobile (Suzhou) Software Technology Company.cloud computing product department Tel: (+86) 18896726087 E-Mail：xiajid...@cmss.chinamobile.com <mailto:xiajid...@cmss.chinamobile.com>
